Majorities reached in some supervisors’ races

Races in Board of Supervisors seats in Districts 2 and 10 have been have been decided, preliminary results show.

As of Friday at 4:45 p.m., the San Francisco elections department released the latest tally from Tuesday’s election. In a surprise count, Mark Farrell of District 2 and Malia Cohen of District 10 leapfrogged over their opponents to garner a majority of votes.

Farrell overcame an early lead by Janet Reilly after just two rounds of ranked-choice voting, according to the department’s website. However, it took 19 counts for Cohen to beat 20 candidates for the District 10 seat. Cohen surmounted leads by Tony Kelly and Lynette Sweet in early rounds until reaching more than the 50 percent needed to win.

Ranked-choice voting allows voters to mark up to three candidates in order of preference for any elected office in the city. After a first round of votes is tallied, the last-place candidate is eliminated. The voters’ next choices are transferred to remaining opponents in subsequent counts until a majority is reached.

Jane Kim and Scott Wiener steadily held their leads to apparent victories in Districts 6 and 8, respectively. Incumbent Carmen Chu, unopposed in District 4, retained her seat.
